I'm not sure if you're joking, but about everything Google provides is free (other than ads I guess).
https://developers.google.com/speed/libraries/
they make money by using the referee information tag as to what sites to index.
All they have to do is replace a script tag. (well a few of them..it looks like the automagically bundle the libraries and dependencies together)
